ASTM B366 WPHB-2: High-Performance UNS N10665 Butt Weld Pipe Fittings
DIPTI METAL INDUSTRIES is a distinguished global ASTM B366 WPHB-2 manufacturer, largest UNS N10665 stockist, and worldwide UNS N10665 exporter of ASTM B366 WPHB-2 Butt Weld Pipe Fittings. The "WP" in WPHB-2 stands for "Wrought Pipe," indicating fittings produced from wrought materials, ensuring superior structural integrity and reliability. "HB-2" designates the material as UNS N10665 (commonly known as Hastelloy B-2 or Alloy B-2 / W. Nr. 2.4617), a specialized nickel-molybdenum alloy.
UNS N10665 (Hastelloy B-2 / Alloy B-2 / W. Nr. 2.4617)
UNS N10665, or Hastelloy B-2, is a nickel-molybdenum alloy developed for outstanding resistance to reducing chemical environments. It builds upon the Hastelloy B series with a tightly controlled chemical composition that provides significantly improved thermal stability, thereby minimizing susceptibility to embrittlement and loss of corrosion resistance in the weld heat-affected zone. Its high molybdenum content (typically around 28%) and very low chromium content (max 1%) are critical for its performance. Key properties include:
Exceptional Hydrochloric Acid Resistance: Offers superb resistance to HCl at all concentrations and temperatures, a hallmark of the Hastelloy B family.
Superior Resistance to Strong Reducing Environments: Highly effective in other non-oxidizing acids like concentrated sulfuric acid, phosphoric acid, and acetic acid.
Improved Thermal Stability: Engineered to resist the formation of deleterious intermetallic phases in the weld heat-affected zone, ensuring consistent corrosion resistance after welding.
Resistance to Pitting and Crevice Corrosion: Good performance against localized corrosion in relevant reducing chemical media.
Good Weldability & Formability: Can be fabricated using standard nickel-alloy welding and forming practices, with the improved thermal stability offering greater versatility in manufacturing.
Our ASTM B366 WPHB-2 fittings ensure robust and reliable connections, maintaining system integrity in critical process piping where strong resistance to hydrochloric acid and other aggressive reducing chemicals, combined with excellent weldability and thermal stability, is paramount.
